DENVER (AP) — Julio Teheran took the mound Wednesday night for the Atlanta Braves with the best ERA in the majors. He left after his worst outing of the season.
Teheran allowed 10 hits and seven runs, both season-highs, in 6 1/3 innings, as the Colorado Rockies beat theBraves 8-2.
He had won a career-best four consecutive games, with a 1.23 ERA in that span, but he gave up three runs in the first.
"It wasn't my day from the first inning," Teheran (6-4) said. "I was trying to compete the whole game. I know it was a tough day for me. I'm just glad that I was able to compete and get through six innings."
Tyler Matzek pitched two-hit ball for the first seven innings of his major league debut for Colorado before faltering in the eighth.
The left-hander retired the first 13 hitters and 21 of 23 before allowing three straight singles to start the eighth. He is the third Colorado pitcher in the last six days to make his debut.
Matzek (1-0) allowed two runs on five hits and struck out seven in seven-plus innings. He also had his first hit and run scored. The Rockies had lost 11 of 12.
Teheran (6-4) allowed an RBI double by Drew Stubbs and Corey Dickerson's two-run triple in the first. His ERA jumped from 1.89 to 2.41.
Troy Tulowitzki and Justin Morneau had three hits each for Colorado.
Matzek, who had control problems coming up through the minors, breezed through the first four innings on 39 pitches. Atlanta hit three balls hard, including a line drive by Teheran snared by Morneau to end the third.
"He has good stuff, 94-95 mile an hour fastball," Braves manager Fredi Gonzalez said. "The whole day you're talking to guys, 'Hey, this guy sprays it around a little bit. Be patient. I'm not sure how many three-ball counts he got into, if any."
Matzek went to three-ball counts on two batters — Freddie Freeman in the first and Andrelton Simmons in the fifth.
Morneau couldn't come down with Justin Upton's single with one out in the fifth to give the Braves their first baserunner. The Coors Field crowd acknowledged Matzek's early work with applause after Upton's hit.
Chris Johnson followed with a single to right but Matzek retired the next two batters to get out of the inning.
"He was pretty good," Simmons said. "We didn't do a good job of hitting strikes. He didn't do much. He threw a fastball and a slider the whole game pretty much, and we didn't hit. You got to give him some credit, but we got to take some blame, too. You got to be better."
Johnson, Tommy La Stella and Simmons singled to start the eight and make it 8-1. Franklin Morales came on and gave up a two-out RBI single to B.J. Upton before getting Freeman to fly out
The Rockies made it 4-0 in the third when Tulowitzki scored on a sacrifice fly by Stubbs.
Josh Rutledge scored from third when Tulowitzki, who singled, was caught in a rundown between first and second in the fifth. Stubbs and Dickerson led off the sixth with consecutive doubles to give Colorado a 6-0 lead.
